This section describes routines for importing and exporting data into
and out of Data Explorer.
This includes support for Data Explorer (<TT>.dx</TT>)
files, as well as
industry-standard netCDF files.

Files in the Data Explorer format
(see <A HREF="usrgu024.htm#HDRDATMOD">Chapter 3. "Understanding the Data
Model"</A> in <I>IBM Visualization Data Explorer User&#39;s Guide</I>)
can be imported by the

routine and exported by the

Data Explorer can accept industry-standard netCDF files, which describe only a
subset of the Data Explorer data model capabilities.
For example, netCDF files are limited to regular
data.
This routine is provided for compatibility with other
systems that use netCDF.
